I've had the weirdest "period" ever. Spotting for 7 days brown, pink and just a little reddish without pain (and it started one week before my period starts usually) and yesterday I decided to have sex with my boyfriend since I was barely spotting. Today I woke up with a little pain in my uterus and felt like a blood clot going down but it was like egg white, transparent with some blood lines. Now I have more intense pain and pink watery spotting. Do you think I could be pregnant or having an early miscarriage or just having the weirdest period ever ? sorry for being so explicit.
